6 Claims.

The present invention relates to a water-cooled wire block for wiredrawing machines and particularly to a block having associated therewitha structure by which cooling fluid is directed against A the inside ofthe rim of the block opposite to the the inside of the block. asshownfor example, in

the Tideman Patent No. 1,497,959, dated June 1'7, 1924. In this patentthe cooling fluid does not all reach the inner surface of the rim wherethe cool- 15 ing action is required and'as a result a relatively largeamount of cooling fluid is necessary to assure a satisfactory coolingaction. The principal object of the present invention is to provide fora more complete cooling of the rim of. the wire block 20 by directingthe entire flow of fluid against the portion of the block where thecooling action is necessary.

To assure a more complete cooling of the wire I block by the coolingfluid flowing over the inner 25 surface of the rim, the presentinvention provides for the formation of inwardly extending cooling ribson the inside of the rim which retard the downward movement of thecooling fluid on the rim and provide for more complete cooling there- 30of. These ribs also provide for reinforcement of the rim so that the rimthickness may be less and accordingly permit a more complete cooling ofthe outer surface of the rim.

Other and further objects and advantages of the 35 invention willhereinafter more fully appear from the following detailed descriptiontaken in connection with the accompanying drawing in which- Fig. 1 is aplan view of a block embodying the 40 invention.

Fig. 2 is a sectional view through the block of Fig. 1;

Like reference characters refer to like parts in the different figures.45 With reference to the drawing, and particularly to Fig. 2, the wireblock I has a rim 2 having an outer substantially cylindrical surface 3at the upper part thereof, and a slightly conical surface 4 below thesurface 3. The wire as it comes from 5 the die is wrapped around thesurface 4, being guided onto the surface 4 by a substantially radiallyextending flange 5 having its outer surface 6 extending outwardly andslightly downwardly from the rim 2 at the lower edge of the surface 4.55 A cylindrical flange 1 extends downwardly from the outer edge of theflange 5. The rim 3 extends below the flange 5 for a purpose which willhereinafter appear.

The wire block 'I has a hub 8 integral with the rim of the block bywhich the block is secured to a 5 suitable driving shaft, not shown. Thehub has an integral radially extending flange 9 which, at its outer end,has a cylindrical flange I 0 extending upwardly to apositionsubstantially in line with the upper edge of the surface 4. Aradial flange 10 II integral with the rim connects the rim to the upperend of the cylindrical flange. Suitable reinforcing webs I2 may beprovided betweenthe hub and the cylindrical flange Ill for strengtheningthe block. Positioned inwardly of the rim 2, and on the underside of theradial flange II, is a short downwardly extending flange I3 for apurpose which will be apparent later.

The block I is positioned above a ring I4 which may be an integral partof the base of the wire drawing machine, or which may be mounted on theupper side of the base, as desired. In either event the ring I4 has acentral opening I5 and upwardly extending cylindrical flanges I6 and I!concentric to the opening I5 and spaced apart to define a ring-shapedtank I8. The outer flange I! is slightly larger in diameter than the rim2 I adjacent the bottom thereof to extend around the lower edge of therim, and the inner flange I6 extends upwardly to a point just below theradial flange II of the block. vIt will be understood, of course, thatthe block and ring are held in predetermined relation to each other bypositioning the supporting bearings for the drive shaft of the block inthe base so that during rotation of the -block the latter and the ringare in the relation shown in Fig. 2.

The upper end of the flange I6 has an annular chamber I9 to which fluidis directedby a hollow post 20 integral with the flange I6. 1 outwardly40 extending ports 2I intersecting the chamber I 9 provide for thedischarge of cooling fluid from the chamber radially outwardly againstthe inside of the rim adjacent to the upper part of the surface 4. ofthe'rim, and the fluid flows down over the inner surface of the rim andinto the tank I8. The cooling fluid is thus directed horizontallyagainst the inside of the block so that it flows downwardly over theportion 4 of the rim about which the wire is coiled; the chamber I9 isthus located within the block as least as high as the lowermost edge ofthe portion of the block about which the wire is coiled. From the tankthe cooling fluid passes through an outlet pipe 22 to a suitablecollecting tank. A pipe 23 connecting to an inlet port 24 provides forthe admission of cooling fluid to the hollow post 29. The chamber andopenings 2i define a nozzle for directing the cooling fluid against therim.

Inwardly extending radial flanges 25 are located on the inside of therim 2 to retard the flow of cooling fluid downwardly into the collecting tank. The upper flange is positioned slightly below the openings 2i,and the lower flange, which is somewhat wider, is in line withtheradially extending flange 5. Through the action of the cooling fluidflowing over the flanges 25, the rim of the block about which the wireis coiled, is maintained at the desired low temperatime without thenecessity for an excessive volume of cooling fluid.

Splashing of the fluid adjacent the nozzles which are formed by thechamber l9 and openings 21 is limited by an upwardly extending flange 25substantially in line with the flange it. The flange 26 is slightlysmaller in diameter than the depending flange it, but in substantiallythe same radial plane, as will be apparent. Further splashing of thecooling fluid is prevented by the downwardly extending flange l on theblock which extends into an annular recess 2'5 provided by the ring 56.

It will be understood that the circulating and cooling apparatus forthefluid, which is shown in applicants copending application, Serial No.208,633, filed May 18, 1938, may be incorporated in this device for moreaccurately controlling the temperature of the rim of the block.
